IMPROVEMENT IN ALPHABET-CASES.

Specification forming part of Letters Patent No. 146,565, dated January20, 1874; application filed December 22,1873.

To all whom it may concern:

Be it known that I, WILLIAM F. BAADE, ot` the city of Buffalo, in thecounty of Erie and State of New York, have invented certain new anduseful Improvements in Alphabet- Cases, ot which the i'ollowingis aspecification:

This invention relates to object-teaching devices; 'and it consists inthe combination of two or more adjustable or movable alphabets,V

and one or more pictures on a movable belt or apron, so arranged thatdifferent objects or pictures may be presented, the alphabet being soconstructed and arranged upon movable surt'aces that words, figures, orsentences can be built up or presented in such a manner that thepictures or other objects connected therewith, as well as other matter,can be explained thereby without the necessity of removing the lettersor pictures from the case.

In the accompanying drawings, in which like letters represent like partsin the several iigures, Figure 1 is a front eleva-tion of my saidinvention; Fig. 2, a back view of the same, showing a slate connectedtherewith. Fig. 3 represents a vertical longitudinal section through thecenter of the case.

A is the case; B, the top or front; C, a series ofgrooves or channelscut through and arranged lengthwise of the same. l) is an open spacenear the top of the case, through which the letters and figures areseen. Eis an open space, through which the pictures are exposed. F is achannel in the face B, through which projects a thumb-piece, G, from thepicture bolt or apron, and by which it is moved.

The letters H represent the thumb-pieces for moving the alphabet apronsor belts, and the letters I represent the said aprons or belts. They areall arranged to move upon a stationary fixed support, J., which isrounded at both ends, as shown in the drawing, andforms a table orsupport for the said belts at the top, for the alphabet, and also thepicture-belts.

There are as many belts or aprons as there are-alphabets or sets ofpictures. The alphabet-belts are all arranged so as to be easily movedback and forth by means ot' the thumbpieces H, while the picture-belt isso constructed and arranged that it canbe moved by the thumb-piece G ina direction continuously for= ward or back, as maybe desired; andifrequired, the alphabet-belts may be moved in a similar manner. I haveshown the picturebelts arranged lengthwise of the case, but it can beplaced crosswise, which might, in some cases, be preferred. K, in Fig.2, represents the slate as set in the back of the case. Fig. l, a top orface view of the belts are shown by dotted parallel lines, marked I, thenarrow parallel lines representing the alphabet-belts, and the wide onethe picture-apron.

All ot' the belts I have one or more alphabets and ii gures printed orotherwise marked thereon; and it can be readily seen from thisdescription and drawings hour any word or sentence may be presented bybringing the proper letters to view, in the manner and by the meanshereinbefore mentioned.

I claim as my invention- 'lhe combination of the case A, having theopenings or channels C C, with the series of movable and adjustablealphabet-belts I, substanti-ally as and for the purposes described.

WILLIAM F. BAADE.
